Perhaps you should try some spelling variations:
xiaotong chen » xiaotong zhang, xiaoguang chen
binh thang » binh thanh, binh thuan, binh tran
chen chan » chen chuan, cheung chan, chen chung
dato yang » dato wan, dan yang, daun yang
bin zhang » li zhang, jia zhang, jie zhang
yao yang » yang yang
wang » wan, lang

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wing) xiaotong chen chan ((dato yang) OR (yao yang)) ((bin zhang) OR (binh thang)) zhi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wing) xiaotong chen chan ((dato yang) OR (yao yang)) ((bin zhang) or (binh thang)) zhi ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wing) xiaotong chen chan ((dato yang) OR (yao yang)) ((bin zhang) or (binh thang)) zhi ;*.
